Multiplicity refers to cardinality in UML diagrams. It represents the number of objects in one class related to the number of objects in another class. A multiplicity can be modeled in the following ways:
- By using a specific value such as 1, 2, 4, etc.
- By using a range of values such as 2..4 or 1..4
- By using a combination of range and specific value 1..*, 4
